SAFETY INFORMATION FOR USERS OF LP-GAS

Propane (LP-Gas)is a flammable gas which can cause fires and explosions. In its natural state, propane is odorless and colorless. You may not know all the following safety precautions which can protect both you and your family from an accident. Read them carefully now, then review them point

by point with the members of yourhousehold. Someday when theremaynotbeaminutetolose,everyone'ssafetywilldepend on knowing exactly what to do. If, after reading the following information, you feel you still need more information, please contact your gas supplier.

LP-GASWARNING ODOR

If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP-Gas.That's your signal to go into immediate action!

Donotoperateelectricswitches,lightmatches,useyourphone. Do not do anything that could ignite the gas.

Get everyone out of the building, vehicle, trailer, or area. Do that IMMEDIATELY.

Close all gas tank or cylinder supply valves.

LP-Gasis heavier than air and may settle in low areas such as basements. When you have reason to suspect a gas leak, keep out of basements and other low areas. Stay out until firefighters declare them to be safe.

Use your neighbor's phone and call a trained LP-Gasservice person and the fire department. Even though you may not continue to smell gas, do not turn on the gas again. Do notre-enterthe building, vehicle, trailer, or area.

Finally, let the service man and firefighters check for escaped gas. Have them air out the area before you return. ProperlytrainedLP-Gasservicepeopleshouldrepairtheleak,thencheckand relight the gas appliance for you.

NO ODOR DETECTED - ODOR FADE

Some people cannot smell well. Some people cannot smell the odor of the chemical put into the gas.You must find out if you can smell the odorant in propane. Smoking can decrease your ability to smell. Being around an odor for a time can affect your sensitivity or ability to detect that odor. Sometimes other odors in the area mask the gas odor. People may not smell the gas odor or their minds are on something else. Thinking about smelling a gas odor can make it easier to smell.

TheodorantinLP-gasiscolorless,anditcanfadeundersomecircumstances.For example, if there is an underground leak, the movement of the gas through soil can filter the odorant. Odorants

in LP-Gasalso are subject to oxidation. This fading can occur if there is rust inside the storage tank or in iron gas pipes.

Theodorantinescapedgascanadsorborabsorbontoorintowalls, masonry and other materials and fabrics in a room. That will take some of the odorant out of the gas, reducing its odor intensity.

LP-Gasmay stratify in a closed area, and the odor intensity could vary at different levels. Since it is heavier than air, there may be more odor at lower levels.Always be sensitive to the slightest gas odor. If you detect any odor, treat it as a serious leak. Immediately go into action as instructed earlier.

SOME POINTS TO REMEMBER

Learn to recognize the odor of LP-gas.Your local LP-Gas Dealer can give you a "Scratch and Sniff" pamphlet. Use it to find out what the propane odor smells like. If you suspect that your LP-Gas has a weak or abnormal odor, call your LP-Gas Dealer.

Ifyouarenotqualified,donotlightpilotlights,performservice, or make adjustments to appliances on the LP-Gassystem. If you are qualified, consciously think about the odor ofLP-Gasprior to and while lighting pilot lights or performing service or making adjustments.

Sometimes a basement or a closed-uphouse has a musty smell that can cover up theLP-Gasodor. Do not try to light pilot lights, perform service, or make adjustments in an area where the conditions are such that you may not detect the odor if there has been a leak ofLP-Gas.

Odor fade, due to oxidation by rust or adsorption on walls of new cylinders and tanks, is possible. Therefore, people should be particularly alert and careful when new tanks or cylinders are placed in service. Odor fade can occur in new tanks, or

reinstalled old tanks, if they are filled and allowed to set too long before refilling. Cylinders and tanks which have been out of service for a time may develop internal rust which will cause odor fade. If such conditions are suspected to exist, a periodic snifftestofthegasisadvisable.Ifyouhaveanyquestionabout the gas odor, call your LP-gas dealer.Aperiodic sniff test of the LP-gas is a good safety measure under any condition.

If, at any time, you do not smell the LP-Gasodorant and you think you should, assume you have a leak. Then take the same immediate action recommended above for the occasion when you do detect the odorizedLP-Gas.

If you experience a complete "gas out," (the container is under no vapor pressure), turn the tank valve off immediately. If the container valve is left on, the container may draw in some air throughopeningssuchaspilotlightorifices.Ifthisoccurs,some new internal rusting could occur. If the valve is left open, then treat the container as a new tank.Always be sure your container is under vapor pressure by turning it off at the container before it goes completely empty or having it refilled before it is completely empty.

WATER VAPOR: A BY-PRODUCTOF UNVENTED ROOM HEATERS

Water vapor is a by-productof gas combustion.An unvented room heater produces approximately one (1) ounce (30ml) of water for every 1,000 BTU's (.3KW's) of gas input per hour.

Unvented room heaters must be used as supplemental heat (a room) rather than a primary heat source (an entire house). In most supplemental heat applications, the water vapor does not create a problem. In most applications, the water vapor enhances the low humidity atmosphere experienced during cold weather.

The following steps will help insure that water vapor does not become a problem.

1.Besuretheheaterissizedproperlyfortheapplication,including ample combustion air and circulation air.

2.If high humidity is experienced, a dehumidifier may be used to help lower the water vapor content of the air.

3.Do not use an unvented room heater as the primary heat source (an entire house).

GENERAL INFORMATION

This is an unvented gas-firedheater. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventilation air must be provided.

Keeproomareaclearandfreefromcombustiblematerials,gasoline and other flammable vapors and liquids.

Unvented gas heaters are a supplemental zone heater. They are not intended to be a primary heating appliance. Water vapor produced by an unvented heater can create moisture problems in a home when operated for extended periods of time.

During manufacturing, fabricating and shipping, various components of this appliance are treated with certain oils, films or bonding agents. These chemicals are not harmful but may produce annoying smoke and smells as they are burned off during the initial operation of the appliance; possibly causing headaches or eye or lung irritation. This is a normal and temporary occurrence.

The initial break-inoperation should last2-3hours with the burner at the highest setting. Provide maximum ventilation by opening windows or doors to allow odors to dissipate.Any odors remaining after this initialbreak-inperiod will be slight and will disappear with continued use.

This appliance must not be used with glass doors in the closed position. This can lead to pilot outages and severe sooting outside the fireplace.

Do not use this room heater if any part has been under water. Immediately call a qualified service technician to inspect the room heaterandreplaceanypartofthecontrolsystemandanygascontrol which has been under water.

WARNING: This appliance is equipped for (natural or propane) gas. Field conversion is not permitted.

High Altitude

When installing this unit at an elevation above 2,000 feet (in the United States), it may be necessary to decrease the input rating by changing the existing burner orifice to a smaller size. Generally, input should be reduced 4 percent for each 1,000 feet above sea level. However, if the heating value of the gas has been reduced, this general rule may not apply. Check with local gas utility for proper orifice size identification.

23099-1-0707

Page 7

PROVISIONS FOR ADEQUATE COMBUSTION & VENTILATION AIR

This heater shall not be installed in a confined space unless provisions are provided for adequate combustion and ventilation air.

The National Fuel Gas Code defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8m3 per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the spacein which theappliances are installed, through openings not furnished with doors, are considered a part of the unconfined space.

Unusually Tight Construction

The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is defined as construction where:

a.Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm or less with openings gasketed or sealed, and

b.Weather-strippinghasbeenaddedonopenablewindowsanddoors,and

c.Caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between

wall-ceilingjoints,betweenwallpanels,atpenetrationsforplumb-ing, electrical, and gas lines, and at other openings.

If your home meets all of the three criteria above, you must provide additional fresh air.

Warning: If the area in which the heater may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction,provideadequatecombustionandventilationairbyoneofthe methods described in the National Fuel Gas Code,ANSI Z223.1, Section 5.3. or applicable local codes.

Example of Large Room with 1/2 Wall divider.

Figure 1

The following formula can be used to determine the maximum heater rating per the definition of unconfined space:

Btu/Hr = (L1 + L2)FT x (W)FT x (H)FT x 1000 50

If the area in which the heater may be operated is smaller than that defined as an unconfined space, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, Section 5.3.
